Numbness and tingling of the hands and/or feet can have many causes.  Pressure on a nerve is rare, more common causes are poor circulation (caused by tight muscles, constricted blood vessels, or tight connective tissue, as examples) and toxicity (diabetes and chemotherapy are examples of this).  At GentleBay Sarasota Chiropractic, we treat neuropathy/numbness/tingling with a combination of gentle manual therapies and stretching, with very good success.
